Fuel system or backfire is what I believe happened to it. The vehicle is available for inspection upon request. My safety was severely put at risk because the car exploded and caught fire while I was inside the car and fire came through the dash and air conditioner slots, anything could of happened whether shrapnel or burn. this also put others at risk if my spouse was in the car with me or the apartment complex I live in could have caught fire and endangered multiple people. No the issue has not been seen or confirmed by a dealer or service center. Yes the vehicle has been inspected by state fire marshal. No there was no warning lights or problems at all. We drove the car the night before, everything was normal and nothing was showing on the dash and the next day I jumped in, put my seat belt on and started the car to make sure it was running good and it exploded and caught flames.
